WATER-HEATER.

Application filed December 27, 1916.

To all "whom it may concern:

Be it known that we, SAMUEL J. MAC- lliULLAN and J OHN M. ULMER, bothcitizens of the United States, residing at l/Villiamsport, in the countyof Lycoming and State of Pennsylvania, have invented certain new anduseful Improvements in Water-Heaters; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art .to which it appertains tomake and use the same.

This invention relates to water heaters of the sectional magazine feedtype and has for its object to provide a heater of this character whichwill be simple in construction, comparatively inexpensive to manufactureand more ellicient in action than those heretofore proposed.

With these and other objects in View the invention consists in the noveldetails of construction and combinations of parts more fully hereinafterdisclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all theviews Figure 1 is a transverse sectional view of a water heater made inaccordance with this invention;

Fig. 9 is a side elevational view of the parts shown in Fig. 8.

1 indicates any suitable support for the water heater, but preferably ofthe channeled form shown, 2 the individual sectional heating membersprovided with the flue spaces 3, and the hollow legs 4, and theconnections 5 with the return manifolds 6, connected with the returnpipes 7, all as will be clear from the drawings. 8 represents the hotwater pipe leading from the 1nanifold 9 to the individual radiators ofthe heating system, and said manifold 9 is connected with the individualheating elements 2 as by the plurality of connections 10. Eachindividual heating unit 2 is provided with the substantially straightinner surface 12 bordering the combustion chamber 13 and with thesubstantially straight surface 141 disposed at an angle to said surface12 as indicated. Each of said heating units 2 is further provided withthe substantially straight surface 15 which is substantially parallel tothe outer surface 17 and which borders the magazine space 16. Locatedinside the magazine space 16 are the supporting means 18 on which reststhe manifold 9. At or near the lower end of each surface 15 there isprovided the projection or solid lug 19 for a purpose now to bedescribed.

In water heaters of the type made the subject of this invention, it isdesirable to provide an automatic feed for the coal and to this end themagazine space 16 is restricted at or near its bottom by means of themember 20 which is provided with the annular space 21 for theaccommodation of water and with the overhanging lip 22 adapted to restupon the lugs 19 with which the individual units 2 are provided. Theextreme ends 23 of said restricting member 20 also rest upon or aresupported by the end casings 25 and 26 of the heater, the said. casings25 and 26 being provided with the orifices 27 and 28 respectivelythrough which said ends 23 are adapted to project, as will be clear fromFigs. 2, 3 and 4 of the drawings.

Said casings 25 and 26 are also provided with lugs 29 to accommodate theoverhanging lips 22 of the member 20, as will be clear from Figs. 3 anda of the drawings.

Said member-.20 is provided with the hot water pipe connections 30 and31 adapted to afford a circulation through the space 21 and to conveythe said hot water to convenient points for use when desired.

The said choking member 20 is also provided with the passage or hole 32through which coal or fuel 33 may pass by gravity down into thecombustion chamber 13.

Located preferably above said restricting passage 32 is the oscillatingrod or member 3i provided with the fin or lip35 adapted to agitate thecoal 33 and thus cause its more even distribution in the combustionchamber, as will be presently described. Said oscillating rod 34.extends to the out.- side of: the heater as indicated in Figs. 2, 3 andl, so that the coal may at all times be conveniently agitated, to insurean even automatic 'fee d thereof.

It will thus be seen that the coal 33 rests betweenthe straight parallelsides 15 of the individual sections, and upon the restricting member 20,so that a portion thereof passes under the action of gravity through therestricting passage 32 and down into the combustion chamber 13. Locatedin the co nbustion chamber 13 are the inclined grates 40 supported attheir lower ends as upon the lugs ll and at their upper ends upon themember -12 which may be hollow as shown and also provided with a waterspace 4i3if. The lndividual'grate members 44 are conveniently pivoted ason the rods 45,

desired.

and saidmembers 44 are providedwith the extendingshanks 46 eachconnected to the reciprocating man as by the individual pivots 4C8. Itthus results thatv by.reciproeating the rod- $7 each of: the individualmembers 44 willbe moved from their full line position shown in Fig; 6 totheir fullas seen in Fig. 6 the said meeting edges 49 and =50 haveseparated so that the ashes may readily fall down into the spaces 52between the individual members 4st and be caught between the surfaces 53and 5liof said members a l all as will be clear from Fig. 7 0f thedrawings. When new the bar 47-is reversed or moved toward the left asseen in Fig. 6, the curved surfaces 54: of the indi vidual members 44will revolve under the ignited-coal, resupport the same and permit theashes to pass down between the surfaces 53 and 5430f the said members44. The re ciprocatingrods 47 are conyeniently led to the outside of theheater and operated by any suitable means as for example the levers 56see Figs. 2 and In' the form of; heater shown in Figs. 1. and 2, theindividual sections 2 may be conveniently secured to the manifolds 6 and9 by the screw threaded connections 5 and 10 respectiyely, in the formshown in Fig. 3, tie rods such as 60 may be also used to holdthesections 2and. other parts together while in the form shown in Fig.4, the hollow nipples 61 provided: with the opposed tapered cone likesurfaces 62-may be employedovherever desired to secure the partstogether. Further in the constructionillustrated in Fig. 4; the,inclined: grates are composedof a plurality of stepped sections 401 alndl-O2, the outer or lower edge or endof the grate 401 being stepped inthe ledge 65, and the inner or upper edge ofthe grate r02 beingstepped-in the ledge 66 c-arriedby the bar6 7- as shown. Otherwise theconstruction of the grates is ormay be the same as illustratedin Figs. 12.and 3.

The operation of this improved heater will: be clear from the foregoingbut-may be briefly sulmn'arized as follows The. individual heatingsectionsare con veni'ently. castin substantially. the form shown, andare secured-totheir corresponding manifolds 6: and 9. and 1 otherassociated parts by any. suitableand wellknown means as indicated:'Ihechoke member20 being. 1n place and the. stirring rod34- having itsfin extending downthroughthe orifice 32- of; said mjember. 20,- coal isintroduced through any. suitable ,door such as 70, and is permitted. to.automatically feed down and uniformly distribute itself over theinclined grates such 215340. The fire beinglighted theprodu'cts ofcombustion .p ass up through In other words, it is an important feature.

ofthe inventionthatinclined :grat'es are, as sociated with a watercooledchoke member such as 20. provided with an agitator such as 35, for sucha construction insures a more constant automatic feed-ofthe fuelandrcquires less attention than would otherwise be possible. In additionto this by inclining the fin 35'to the. right'or left so as to par:

tially close the opening 32, the quantity -013- coal passing throughsaid opening can be restricted atwill and therefore, a. rough regulat1on of the fire be had at all times. In addition, if it should bedesired that the automatic feed of coal be substantially uniform bothwhen the magazine is full and when it is only partially full the fin 35may be held in an inclined position in the opening 32 when the magazineis first filled, and later adjusted to a more nearly vertical positionas the coal is used up, thus causing a somewhat even feeding pressure tourge the coalv through said opening 32. In order that the coal may beevenly distributed over the grates a0, the control lever 7 6, Fig. 3,may be moved first to one side and then to the other and finally securedto one of the catch members 77 in the desired position. In addition tothis when it is desired to run only one grate, as in the summer time,the fin may be left so inclined as to practically cut off coal from theother grate.

It is obvious that those skilled in the art may vary the details ofconstruction as well as the arrangement of parts without departing fromthe spirit of the invention and therefore it is not desired to limitthis invention to the above disclosure except as may be required by theclaims.
